Tourism Management System (C++ | OOP)

This project is an Object-Oriented Programming application written in C++ that simulates the management system of a tourism agency.
It demonstrates advanced OOP concepts such as inheritance, polymorphism, operator overloading, templates, exception handling, STL containers and design patterns.

---

Project Overview

The application models the main components of a tourism agency system including:

• clients
• tourist packages
• hotels
• transport services
• accommodation services
• travel destinations
• premium travel destinations
• tourism agency management

The system allows adding, displaying, sorting and managing travel destinations and tourism services using an interactive console menu.

Object-Oriented Programming Concepts Implemented

The project demonstrates multiple OOP principles:

Encapsulation

All classes use private attributes and provide getters and setters for controlled access.

Inheritance

Multiple inheritance hierarchies are implemented:

Destinatie
   ↓
DestinatieTuristica
   ↓
DestinatiePremium

Another hierarchy implements diamond inheritance:

           IServiciuTuristic
            /            \
       Transport        Cazare
            \            /
           PachetTuristic

Polymorphism

Virtual methods allow dynamic dispatch when working with base class pointers.

Example:

virtual void afiseazaDetalii() const = 0;

Operator Overloading

Several operators are overloaded, including:

• << and >> for input/output streams
• +, -, * for modifying prices
• ++ and --
• ==, !=, <
• [] for indexed access

Constructors and Destructors

Each class implements:

• default constructors
• parameterized constructors
• copy constructors
• destructors
• assignment operators

Advanced C++ Features

The project also includes more advanced C++ programming concepts.

Templates

A generic repository class is implemented using templates:

template<typename T>
class Repository
{
private:
    vector<T> items;
};

Template functions are also used for:

• sorting collections
• finding maximum elements

---

Exception Handling

Custom exception classes are implemented:

• TourismException
• InvalidDataException
• FileException
• NotFoundException

Example:

class InvalidDataException : public TourismException
{
public:
    InvalidDataException(const string& msg)
        : TourismException("Date invalide: " + msg) {}
};

---

STL Containers

The project uses multiple STL containers:

• vector
• set
• list
• map

Example:

vector<shared_ptr<Destinatie>> destinatii;
set<string> tari;
list<string> rezervari;
map<string, int> statisticiTari;

These containers are used for storing destinations, reservations and country statistics.

---

Design Pattern – Singleton

The Singleton pattern is implemented for the tourism agency management class.

class AgentieTurism
{
private:
    static AgentieTurism* instance;
};

This ensures that only one instance of the tourism agency exists in the program.
